Answer:

Option (B)

Step-by-step explanation:

Given system of equations is,

x² + y² = 9 ------(1)

[tex]\frac{x^2}{25}-\frac{y^2}{36}=1[/tex] -------(2)

From equation (1),

x² = 9 - y²

Substituting these values in equation (2),

[tex]\frac{9-y^2}{25}-\frac{y^2}{36}=1[/tex]

Therefore, Option (B) will be the correct option.

Answer:

22.4722

Step-by-step explanation:

To answer this question we need to use the distance formula. The distance formula is as follows:

[tex]d = \sqrt{(x2 - x1)^2+(y2 - y1)^2}[/tex]

Now, let's identify what each variable is:

x2 = 13

x1 = -8

y2 = -1

y1 = 7

Next, let's put these into the equation:

[tex]d = \sqrt{(13 - (-8))^2 + (-1 -7)^2}[/tex]

Time to solve the equation:

[tex]d = \sqrt{(21)^2+(-8)^2} \\d = \sqrt{441 + 64} \\d = \sqrt{505} \\d = 22.4722[/tex]

Therefore, the distance between the points of (-8,7) and (13,1) is 22.4722.

Answer:

125

Step-by-step explanation:

82 percent of 65.6 is 125

Answer:

I hope I got your question correctly.

82% of 65.6 is 54.

Step-by-step explanation:

Consider this equation:

P%=[tex]\frac{x}{y}[/tex]

The value of P% here is 82, which is 0.82 in decimal form.

x is unknown

y is 65.6

Simply cross-multiply 65.6 and 0.82.

The result is 53.8 or 54.

Answer:

a. 8.58 (8.57142857143)

Step-by-step explanation:

The sentence "28 is the product of Rhonda's age and 2" can be translated into the following equation as 28 = 2 × r

In this equation, use the variable 'r' to represent Rhonda's age.

The equation states that the number 28 is equal to the product of 2 and Rhonda's age (r).

This equation describes the relationship between the value 28 and Rhonda's age.

If you know the value of 'r', you can solve for 28, and vice versa.

It's a simple way to express the given information mathematically.

Therefore, the given sentence about product of Rhonda's age and 2 is equal to 28 written in the equation form as 28 = 2 × r .

Answer: They ate at the same pace.

Step-by-step explanation: assuming you want to know who ate more faster you can do 18 / 30 and 24 / 4 to find out who ate more in 10 seconds each.

18 / 3 = 6 and 24 / 4 = 6. So they ate at the same speed / pace.

Answer:

1/10

Step-by-step explanation:

[tex]\frac{2}{5} \div 4 = \frac{2}{5} * \frac{1}{4}[/tex]

we multiply by the reciprocal when we work with fractions and division.

Now you just multiply across.

Therefore, you have 2/20, which simplifies to 1/10.

A fraction is a part of a whole.

It is expressed as a quotient, in which the numerator is divided by the denominator.

The simplest form of 2/5 divided by 4 is 1/10.

A fraction is a part of a whole.

It is expressed as a quotient, in which the numerator is divided by the denominator.

Example: 2/3, 5/7, 1/3

We have,

2/5 ÷ 4

= (2/5) / 4

= 2 / (4 x 5 )

We cancel the common factor from the numerator and denominator.

= 2 / (2 x 2 x 5)

= 1 / (2 x 5)

= 1 / 10

We see that there is no common factor to be canceled out from the numerator and the denominator.

= 1/ 10 is our simplest form.

Thus the simplest form of 2/5 divided by 4 is 1/10.

ANSWER:

Answer:

a

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

(a) If

[tex]f(x)=\displaystyle \sum_{n=0}^\infty (-1)^n \frac{(x+1)^n}{(n+1)!}[/tex]

then by the ratio test, the series converges for all x, since

[tex]\displaystyle \lim_{n\to\infty} \left| \frac{ (-1)^{n+1} \frac{(x+1)^{n+1}}{(n+2)!} }{ (-1)^n \frac{(x+1)^n}{(n+1)!} } \right|=\lim_{n\to\infty}\frac{|x+1|}{n+2}=0[/tex]

so the series radius of convergence is ∞ and the interval of convergence is (-∞, ∞).

(b) The series converges everywhere absolutely, because the ratio test for

[tex]\displaystyle \sum_{n=0}^\infty \frac{|x+1|^n}{(n+1)!}[/tex]

also shows the radius of convergence is ∞.

(c) The series converges absolutely, so conditional convergence is moot.
